The invention discloses a door opening and closing control method and system for a vehicle-mounted refrigerator. The control method comprises a setting step, a signal receiving step, a signal processing step, a motor starting step, a stroke detecting step, a comparing step and a braking step. According to the technical scheme, full-automatic door opening and closing of the vehicle-mounted refrigerator are achieved, during production, the Hall stroke needs to be set according to the size of the door body assembly, the duty ratio signal parameter needs to be set according to the rotating speed of the motor assembly during operation, and in practical application, when the vehicle-mounted refrigerator is opened or closed, a door opening signal or a door closing signal is input to the vehicle-mounted refrigerator; the vehicle-mounted refrigerator further judges whether the door opening signal or the door closing signal is qualified or not, if yes, the motor assembly is controlled to be started, the rotating speed of the motor assembly is controlled according to the duty ratio signal parameter after the motor assembly is started, and the rotating stroke of the motor assembly is controlled according to the Hall stroke, so that human intervention on opening and closing of the door body of the vehicle-mounted refrigerator is effectively avoided; and the damage to the door body of the vehicle-mounted refrigerator is effectively avoided.
本发明公开了一种车载冰箱开关门控制方法以及控制系统,控制方法包括设置步骤、信号接收步骤、信号处理步骤、电机启动步骤、行程检测步骤、比较步骤以及制动步骤。本技术方案实现了车载冰箱的全自动开关门,生产时需要根据门体组件尺寸设置霍尔行程以及根据电机组件运转时的转速设置占空比信号参数,实际应用中在对车载冰箱进行开门或者关门操作时,向其输入开门信号或关门信号,车载冰箱再进一步判断开门信号或关门信号是否合格,若合格则控制电机组件启动,电机组件启动后根据占空比信号参数控制其转速,根据霍尔行程控制电机组件的转动行程,从而有效地避免有人对车载冰箱门体开关的干预,有效避免对车载冰箱门体的损坏。
